Adding to that, Your ISP has a lot of zombied, sick clients on it. I find it hard to believe the number of zombied computers on the RoadRunner network trying to hit my mail server. Your upstream ISP server is letting a lot of junk through by lack of control by your ISP. Now, they've been black listed by spamhaus.org for that content. Unfortunately you chose a bad ISP. Complain to them and/or threaten to take your business elsewhere, but their problem is so large, they probably can't even begin to put a dent in it now! Glenn
